The present invention is directed to a grease-cutting detergent composition that exhibits a stable foaming profile when used with non-enclosed automatic dishwashers. The composition can be sold in a concentrated form or in ready-to-use (RTU) diluted form. The concentrated compositions are formulated to be diluted with water before use. The RTU formulas are intended for as-is usage. In one embodiment the concentrated compositions comprises a) from about 0.25% to about 10% of a surfactant, b) from about 4% to about 8% of an alkalinity source, c) from about 0.1% to about 4.0% of a hydrotrope, d) from about 0.001% to about 2.0% of a builder, and e) from about 0.01% to about 3.0% of a thickener. In another embodiment an RTU formulation comprises a) from about 50 ppm to about 80 ppm of a surfactant, b) from about 45 ppm to about 75 ppm of an alkalinity source, c) from about 20 ppm to about 45 ppm of a hydrotrope, d) from about 0.1 ppm to about 5 ppm of a builder, and e) from about 5 ppm to about 18 ppm of a thickener. The concentrated compositions have a pH of from about 12 to about 13, preferably from about 12.40 to about 12.60, and most preferably from about 12.45 to about 12.55. The concentrated compositions preferably are diluted by the end user at a ratio of from about 1:700 to about 1:1100 parts cleaning composition to water, more preferably from about 1.800 to about 1:1000 parts cleaning composition to water. The present invention also relates to methods of preparing and using the detergent compositions
